BACKGROUND: Sulfonylurea is recommended to be taken before meal. But since premeal administration is against Koreans usual medication habit, it can be the cause of poor compliance. Such recommendation is based on the results of a few clinical trials about appropriate medication time. But most of the clinical studies had a limitation : observe only acute effects of medication, subjects were only healthy volunteer. So the chronic effect of sulfonylurea of each kind must be validated. METHODS: From 1996 May to 1996 July, data were collected from diabetic patients who visited an university hospitals for managing diabetes and used a intermediate-acting sulfonylurea. The subjects were randomized to two groups of premeal group and postmeal group, by chart number and were asked to take the previous medicine according to assignment. After 1 month medication, mixed meal tolerance test was done with 300Kcal carbohydrate, 400+/-50Kcal diet. The subjects were switched to the other group and 2nd mixed meal tolerance test was done 1 month later. The Area under curves was calculated in preand post-prandial glucose curve and was compared by paired t-test. RESULTS: During the study period, total 16 diabetic patients were enrolled. There was no significant statistical difference between pre-prandial group and post prandial group in AUC. CONCLUSIONS: Intermediate-acting sulfonylurea can be administered at any time in relation to meaL.

Among the skeletal tuberculous spondylitis is high incidence and curable disease, if early diagnosis and treatment are possible. We reviewed clinical manifestations and radiologic analysis of 30 cases tuberculous spondylitis from May 1983 to Sept. 1986, at Yeungnam medical center, Yeungnam University. The results were follows: 1. The frequent involve sites were thoracolumbar vertebra. 2. The continuous lesion is 86.7% of the all cases. 3. The most common type was intervertebral type, and lytic and sclerotic lesion were same incidence. 4. Paravertebral abscess, kyphosis and disc space narrowing were demonstrated more than 80.0% of the cases. 5. Computed tomography was more accurate diagnostic method rather than conventional plain study to evaluation of extent of lesion, involvement of spinal canal and cord, and size and location of paravertebral abscess. And CT guided abscess drainage procedure was helpful to diagnosis and treatment. 6. Ultrasonography was helpful to differential diagnosis between paravertebral abscess and other solid mass, and useful to follow up study of paravertebral abscess after treatment.

Allergic contact dermatitis is a prototype of delayed hypersensitivity reaction. Langerhans cells, keratinocytes and T lyrnphocytes play major roles in the pathogenesis of allergic contact dermatitis. We observed Langerhans cells and keratinocytes in contact sensitized epidermal sheets of mice and performed mixed epidermal cell lymphocytes reaction with normal epidermal cells and contact sensitized epidermal cells to determine the lymphocyte stimulating capacity of contact sensitized epidermal cell. We obtained following results : 1. The Langerhans cells were decreased in number and morphologically damaged in contact sensitized epidermis. 2. Ia antigen expression on keratinocytes was detected in almost all contact sensitized epidermal sheets. 3. The allogeneic lymphocyte stimulating capacity of contact sensitized epidermal cells was greater than that of normal epidermal cells. 4. The allogeneic lymphocyte stimulating capacity of contact sensitized epiderrnal cells was lost after treatment of epidermal cells with anti Ia antibody and complement. From these results, it is conceivable that the contact sensitized epidermal cells can amplify the immune reactions by stimulating the lynphocytes which are infiltrated in contact sensitized epidermis.

Two cases of Bleeding Meckel's Diverticulum Using (99m)Technetium-Pertechnetate Scanning are presented. (99m)TC-pertechnetate was used in the diagnosis of Meckel's Diverticulum by Jewette et al in 1970 for the first time. The affinity of this isotope for the parietal cell of the gastric mucosa makes it ideal for delincating ectopic gastric tissue. It noninvasiveness can be used in early screening test of occult gastrointestinal bleeding in pediatric age group.

Magnetic resonance (MR) is rapidly emerging technique that provides high quality images and potentially provides much more diagnostic information than do conventional imaging modalities. MRI is conceptually quite different from currently used imaging methods. The complex nature of MRI allows a great deal of flexibility in image production and available information, and key points are as follows. 1. MR offers a non-invasive technique with which to generate in vivo human images without ionizing radiation and with no known adverse biological effects. 2. Imaging mechanism of MRI is quite different from conventional imaging modality and for more accurate diagnostic application, It is necessary for physician to understand imaging mechanism of MRI 3. M.R. makes available basic chemical parameters that may provide to be useful for diagnostic medical imaging and more specific pathophysiologic information which are not available by alternate techniques. 4. M.R. can be produced by number of different methods. This flexibility allows the imaging technique to be applicated for particular clinical purpose. Multiplanar and three dimensional imaging may extend the imaging process beyond the single section available with current CT. 5. Future directions include efforts to; a. Further development of hard ware b. More fastening scan time c. Respiratory and cardiac gated imaging d. Imaging of additional nuclei except hydrogen. e. Further development of contrast media f. MR in vivo spectroscopy g. Real time MR imaging

Acute cavitating pulmonary infection with a mycetoma is sometimes occur in immunocompromised patient. Most mycetoma lesions are due to Aspergillus species, and lesion caused by Candida species is rare. So we report an experienced case that pulmonary and rib infection caused by Candida species-'in -AML patient and complete remission with previous reports.
